[Ovmsdev] Fwd: Car remote unlock issue

The non-US cars have an immobilizer that cannot be affected by the CAN bus. Better security but it means that can bus lock/unlock cannot affect the alarm or engine immobilizer. So, yes, expected behavior.

The US cars don't have an immobilizer, and lock/unlock on the CAN bus will also enable/disable the alarm.

Regards, Mark.

> Hi everyone
> When unlocking my Roadster (2.5, EU-Model) via the OVMS-Android-App, the car acknowledges the unlock-command and unlocks the car (everything seems to work like a charm so far).
> But after the car is unlocked I cannot open one of the doors without triggering the alarm. As soon as I open the driver or passenger door the alarm goes off. Looks like the OVMS sends the unlock command to the Roadster, but the Roadster does not disable the car alarm system after the unlock.
> Is that a well knows behavior or can anyone confirm this issue?
